Class practice is based around all students having access to a gmail account.  It can be tedious signing every student up plus there will always be some who don't want one.  At Woodrising we have set up 13 student accounts and 1 trainers account.  They all have the same simple password.  

It really doesn't take that long to set them up and its invaluable for any future training or BFS tutoring.

Suggested format for naming is student01.nnn and traine.nnn where 'nnn' are the initials of your centre or kiosk. Similar for the password - nnn%nnn%

I then hand out slips of paper to each student with their unique logon name and password
